It is preferable that the joint portion 42 is closed so that it cannot be opened and closed during use by sewing or the like from the viewpoint of securing strength against a strong pulling force.

  The pad holder of the present invention has a pad pressing stretchable belt 8 having elasticity in at least the width direction (X direction). The pad pressing stretchable belt 8 is a longitudinal direction of the waist opening 5 and the absorbent pad 7. (Y direction) is arranged between the position which can cover the edge part 71 (refer FIG. 2, FIG. 4), and the wearer's iliac crest 9 is made to be covered with the pad holding | suppression elastic belt 8. (See FIG. 2). Specifically, in the pad holder 1, the pad pressing elastic belt 8 is made of an elastic material having elasticity in the longitudinal direction (Y direction) and the width direction (X direction). 4, the opening edge of the waist opening 5 is arranged from the opening edge of the waist opening 5 to a position that can cover the end 71 in the longitudinal direction (Y direction) of the absorbent pad 7 to be worn. It is formed along the entire circumference. In this manner, the pad pressing elastic belt 8 is formed in a thick, abdomen-like ring shape so that the pad pressing elastic belt 8 covers the upper anterior iliac spine 91 together with the wearer's iliac crest 9 when worn. Has been.

  Both the iliac crest (the portion indicated by reference numeral 9 in FIG. 6) and the superior anterior iliac spine (the portion indicated by reference numeral 91 in FIG. 6) are both anatomical terms. It is. As shown in FIG. 6, the superior anterior iliac spine 91 is a blunt protrusion located at the front lower part of the iliac crest 9. Here, the iliac crest will be described as a fan shape above the iliac body that forms the upper part of the acetabulum. It has a iliac wing that spreads, and is a portion located at the upper edge (portion 9 in FIG. 6) of the iliac wing. A pair of upper anterior iliac spine 91 and iliac crest 9 exist on the left and right sides of the wearer. In FIG. 2, the position of the navel is indicated by reference numeral 10.

The pad pressing elastic belt 8 preferably has a length in the vertical direction (Y direction) of 30% or more of the length of the pad holder 1 in the vertical direction (Y direction). Therefore, it is more preferable that it is 70% or less. In particular, it is preferably 35% or more and 65% or less. It should be noted that the length in the vertical direction (Y direction) of the pad pressing elastic belt 8 and the length in the vertical direction (Y direction) of the pad holder 1 are lines that bisect the length in the pad holder width direction in the natural state. It is the length in each of the front body and the back body when measured along the line CL.
The pad pressing elastic belt 8 is preferably 80 to 210 mm in the longitudinal direction (Y direction) in the natural state, and the pad holder 1 is 230 in the longitudinal direction (Y direction) in the natural state. It is preferably ~ 330 mm, particularly 250-300 mm.

  As described above, the pad pressing elastic belt 8 only needs to have elasticity in at least the width direction (X direction). However, in the pad holder 1, each of the back body 2 and the front body 3 is arranged in the width direction ( It is made of a stretchable material having stretchability in each of the X direction and the longitudinal direction (Y direction), specifically a stretchable sheet, and has stretchability as a whole. Thus, if it has stretchability as a whole, it is easy to wear and fits the body shape of the elderly, and is not painful at the time of wearing. Furthermore, it is excellent in preventing the holder from slipping off and fitting the pad.

  As the stretchable sheet for forming the pad pressing stretchable belt 8, a knitted fabric, a stretchable nonwoven fabric or the like can be used as in the case of the pad holder 1. When a knitted fabric is used, the knitted fabric or mesh By changing the density, the maximum elongation rate and elongation stress to be described later in the width direction (X direction) and / or the longitudinal direction (Y direction) can be adjusted as appropriate, or a strip-like sheet having poor extensibility can be used as a sheet rich in elasticity. It is also possible to use one that is joined by stitching, fusion, or the like and that is adjusted in the width direction (X direction) and / or the longitudinal direction (Y direction) as will be described later. The pad holding elastic belt 8 of the pad holder 1 reduces the maximum elongation rate only in the width direction (X direction) with respect to the longitudinal direction (Y direction) by making the mesh of the knitted fabric forming the pad holder 1 dense. It is formed by folding back that portion and fixing its end to the inner surface (or outer surface) of the holder, and is formed in a double layer. Instead of folding the knitted fabric, the pad pressing stretchable belt 8 is a knitted fabric other than the pad holder 1, an elastic member, for example, a stretchable woven fabric or nonwoven fabric containing polyurethane fibers, a synthetic rubber sheet, natural rubber. You may attach and form a sheet | seat etc.

  As described above, the pad pressing elastic belt 8 uses a knitted fabric having elasticity in the width direction (X direction) and the vertical direction (Y direction) in the pad holder 1, but in the width direction (X direction). ) Only with a reduced maximum extension rate, and the maximum extension rate in the width direction (X direction) is smaller than the maximum extension rate in the longitudinal direction (Y direction). For this reason, the holder is prevented from slipping off and the pad fits well.

Here, the maximum elongation rate is the elongation rate when the material is stretched to a length that cannot be further stretched (the length immediately before material breakage), and the maximum elongation rate is obtained by the following formula (1).
Maximum elongation rate (%) = {(length after stretching−length before stretching) / length before stretching} × 100% (1)

  The maximum elongation rate in the width direction (X direction) of the pad pressing elastic belt 8 in each of the front body 2 and the back body 3 is preferably less than 200% from the viewpoint of preventing the holder from slipping off and providing a suitable wearing feeling. 130 to 190% is more preferable, and 140 to 180% is still more preferable. In addition, the maximum elongation ratio in the longitudinal direction (Y direction) is preferably less than 500%, more preferably 150 to 450%, and more preferably 250 to 350% from the viewpoint of preventing the holder from slipping off and the pad mounting position stability. Is more preferable.

  The pad pressing elastic belt 8 uses a knitted fabric having elasticity in each of the width direction (X direction) and the longitudinal direction (Y direction), but the stretching stress in the width direction (X direction) is the longitudinal direction (Y direction). ) Greater than the elongation stress. For this reason, the holder is prevented from slipping off and the pad fits well. Here, the elongation stress is a load when the elongation rate is expanded to 100%.

  The stretching stress in the width direction (X direction) of the pad pressing elastic belt 8 in each of the front body 2 and the back body 3 is preferably less than 35N, more preferably 10-30N, and even more preferably 15-25N. Moreover, it is preferable that the elongation stress of the vertical direction (Y direction) is less than 30N, 5-25N is more preferable, 7-15N is still more preferable.

  Hereinafter, a method for measuring the maximum elongation rate and the elongation stress in the width direction (X direction) and the longitudinal direction (Y direction) of the pad pressing elastic belt 8 will be described in detail.

Further, the pad pressing elastic belt 8 is cut out so as to be included over a range of at least 60 mm, and the cut out rectangular shape is used as a measurement sample. The sample preparation method is based on the premise that the pad pressing elastic belt 8 is continuously arranged over the entire length of 60 mm. However, the pad pressing elastic belt 8 may be partially divided. It shall be included in this category.
The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the X direction) is the tensile direction. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks when at least a part of the measurement sample is broken is measured to obtain the maximum elongation rate.
However, if the sample for measurement does not break even after 100 N load, the distance between chucks at 100 N load is measured to obtain the maximum elongation rate.
In addition, the tensile stress is defined as the tensile stress when the sample is stretched to 100% by the sample preparation and measurement method in the same manner as described above.
If the sample cannot be taken out from the pad holder to be measured as described above, the sample length, sample width, distance between chucks, and chuck width may be changed as appropriate.

The measurement sample is attached to a chuck of a tensile tester so that the longitudinal direction (corresponding to the Y direction) is the tensile direction. The distance between chucks is 50 mm (the chuck part is a part 25 mm before and after the measurement sample). The measurement sample is pulled at 300 mm / min, and the distance between chucks when at least a part of the measurement sample is broken is measured to obtain the maximum elongation rate.
However, if the sample for measurement does not break even after 100 N load, the distance between chucks at 100 N load is measured to obtain the maximum elongation rate.
In addition, the tensile stress is defined as the tensile stress when the sample is stretched to 100% by the sample preparation and measurement method in the same manner as described above.
When the measurement sample cannot be taken out from the pad holder to be measured as described above, the sample length, the sample width, the distance between chucks, and the chuck width may be appropriately changed.
